1. The closer the force is to the center, the less torque it produces. So a large force would produce a small torque if the lever arm is small and a small force would produce a large torque if the lever arm is large (T=Fr).
2. "Support forces" are not included in calculations because the fulcrum exerts an upward force on the meter stick (canceling it out in the equations).
3. T=Fr therefore the equation would the totaling of the forces and lever arms and setting them equal to each other as such:
(0.22)(0.35) = 0.1m + (0.5)(0.12)
m = 0.17 kg
M*24.8=100*20.2
M=81.45 g
